Borg is a virtual host server to be used to give members access to virtual machines in the space and ultimately replace many if not all the functions of Babbage.
Naming
We are naming this machine after Anita Borg. Also the Borg.
They're currently labeled as BORG1 through BORG6 from bottom to top.
Access
Currently connected to the SPC1601 PDU, we need a better way of adding accounts.
Specs
IBM 3950 M2
- 16 cores total

Logbook
Running Debian
- Needs the non-free bnx2 firmware on a flash drive for the install to work, (could try to add it to the install initrd)
- Something something IBM Calgary IOMMU something something leads to DMA errors and the LSI MegaRaid raid card dosn't work, booting with "iommu=soft" makes it work but may not be ideal

Birth
It is reasonable to say the birth of Borg has been long and difficult, concern has generally revolved around the 3 areas:
- Usage
- Energy Consumption
- Location
Each have been discussed on the mailing list but for summary.
Usage
Borg will have the following uses:
- Shell accounts for members
- Virtualising random machines in the space
- Processing of cams
Energy Consumption
Borg (being a server) could add substantially to our electricity costs. To help this we can offset some of it by the retiring of other machines in the space. It has also been agreed that if it takes up more than 275W regularly then a decision about Borgs future will have to be made. If it goes over 300W we will have to re-think our strategy. These figures are a maximum and equate to about £27 per month in electricity costs. The power consumption will be regularly measured and anyone is welcome to report power consumption levels.
Location
The Rack in the basement.
Potential uses
Please list any machines/uses you think would benefit from virtualisation.
- Shell accounts (from Babbage)
- Cam processing (from Babbage)
- Cross-compiling environment (from Lovelace)
- netboot server (replacing netbootyboxxy).
Current VMs
Please keep this list up to date of virtual machines on Borg. If a machine is created but is not in this list it is liable to be switched off without warning.
